Abstract
An example of a species collection system includes a plurality of spaced-apart electrically conductive collectors and a plurality of emitter electrodes. In some embodiments, at least one emitter electrode is disposed between adjacent ones of the collectors. In some embodiments, the at least one emitter electrode extends beyond the collectors (e.g., in at least one dimension). Collectors may be aligned to a direction of gas flow from an outlet (e.g., of a cooling tower) to facilitate collection while minimizing interference with the gas flow. Different emitter electrodes may be maintained at different voltages. In some embodiments, collectors are attached to a collector frame and emitter electrodes are attached to emitter frame(s) that are electrically insulated from the collector frame. Collectors may span a gas outlet (e.g., of a cooling tower) and emitter frame(s) may be positioned outside of the collectors (e.g., and outside of a periphery of the gas outlet).
